Abstract
A fluid infusion system including a pocketable pump housing with a reservoir cavity with helical coupling features. The system further has a reservoir with an open end that is removable from the reservoir cavity. A removable cap coupled to the housing is also included in the system. The cap has corresponding coupling features, an exterior surface and a tab. The corresponding coupling features couple the cap to the housing while the tab is a ridge that extends away from the exterior surface. The tab has a port to accommodate flow from the reservoir and the port defines an axis of rotation such that torque applied to the tab about the axis of rotation disengages the coupling between the cap and the housing. The system further has a removably coupled guard with a slot defined to immobilize rotation of the tab about the axis of rotation.

21. An apparatus to prevent removal of a reservoir assembly from a fluid infusion system, comprising:
-
a first arm; a second arm coupled to the first arm; and a lock feature between the first and the second arm, the lock feature defined to accommodate a reservoir assembly feature, wherein the lock feature restricts movement of the reservoir assembly feature when the apparatus is placed onto the reservoir assembly. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
